The demonstration project in Zhytomyr was completed in spring 2015. The project area includes five residential building blocks and a day care centre. The project concept was to
- Introduce a demand driven heat supply to customers, by installing individual heat substations with control of heat supply in relation to outdoor temperature.
- Reduce losses in heat distribution by replacing heat distribution pipelines in the area, in total 0.8 km (double pipe)
- Improve efficiency of heat production by installation of new condensing boilers and a heat pump for provision of domestic hot water during summer.
Project results and achievements
The project in Zhytomyr demonstrates best practices in technical design, procurement and project implementation in a small-scale project providing valuable experience and knowhow for the bigger projects to come for rehabilitation of the district heating systems in Zhytomyr. The combination of efforts for introduction of a demand driven heating system, reduction of losses and improvement of production efficiency is expected to bring savings in the order of 40 % and improved services to the just over 600 residents in connected buildings and of the kindergarten with 80 children. The project is also profitable for the utility with an expected payback time of less than six years.
